It depends. I live in the western part of Norway. Our winter could be really cold, but last season was from mid april to end of october. A normal season is may-okt. We have some courses that is open all year as well.
Thank you, blogging is still new to me. Lots to learn, but I hope I will contribute
I am a mid handicapper, and YES, they can make a difference. For example, PRO V1's are designed to spin. Good players who can control spin find this an asset, for people like me, who just want the thing to go straight, it is a disadvantage. There is little difference as far as distance is concerned, but the feel of the ball when chipping and putting is concerned varies a lot. The secret is to find a ball you feel comfortable with. I use Srixon Distance balls. They are as cheap as chips, but I like them, and that's all that counts.
